The LEGO light sensor does not work this way. The voltage output of the sensor
goes down with brighter light. A touch sensor in parallel with a light sensor
when touched will cause a light reading of 100. You cant tell that from a
bright light. Your method of biasing with extra light will only make things
worse. The light and touch sensor double-up method depends on not confusing
bright light with a touch.
